I was wondering if it would be possible to optionally support a ceramic during firing in the kiln with some kind of ceramic support post or rod. This would allow top heavy designs or designs with relatively narrow bases to be be fired without falling over in the kiln. It would also allow complex designs to be properly glazed on the bottom surfaces except for where the post support hole is located. (The support hole could always be plugged or filled later.) You might need to establish some standards such as specific support hole diameters and depths, support post height options, and a maximum value for the height of the ceramic design when placed on the support posts. For example, here's a design of a small cup shown cut in half. You would want the top edge to be glazed so you can drink out of it but obviously it would want to fall over without a supporting post stuck in the bottom cavity at the narrow end.
